UI-TARS-1.5-7B
ByteDance Seed's UI-TARS-1.5-7B, the open 7B checkpoint of the UI-TARS-1.5 GUI agent line: a vision-language model that reads screenshots and writes a reasoning thought followed by its next interface action as text, published as open weights under Apache-2.0.

- This record represents the UI-TARS-1.5-7B weight release in the ByteDance-Seed/UI-TARS-1.5-7B repository, announced 17 April 2025. The model card states a stronger UI-TARS-1.5 model is offered only as early research access on request, and that model, the UI-TARS-desktop application, the paper's earlier UI-TARS checkpoints, and gateway-hosted copies are separate boundaries. Its output is text that names GUI actions; the record covers the model, not any harness that executes those actions.
